Nissan Fairlady/300ZX Z32 Valve Assembly Vacuum Delay (Twin Turbo)

This OEM vacuum delay valve is used on the Z32 chassis to regulate the timing of vacuum signals within the engine control system. It works by slowing or controlling how quickly vacuum pressure reaches components such as EGR controls, boost-related systems, or other emissions devices. This helps stabilize engine operation and ensures proper sequencing of vacuum-controlled functions rather than allowing abrupt changes.
